SEASHELLS offers a handsomely illustrated introduction to the fascinating world of the mollusk, covering topics such as shell structure, classifications, gastropods, bivalves (scallops, oysters, clams, and members of the nautilus family), land and tree snails, and the ethics of shell collecting. Few natural objects are as beautiful as the shells of mollusks. Shells occur in all the world's oceans, from the polar regions to the tropics, and few beaches are found without some shells at the waterline. Still more shells can be found in fresh water, in all habitats from the tiniest streams to the largest lakes. No artist can reproduce their stunning range of colors, markings, and textures; their sizes vary from a fraction of an inch (a few millimeters) up to giants greater than 2 feet in length (61 centimeters). Illuminating in both words and remarkable pictures, SEASHELLS is just one title in the acclaimed Creatures of the Ocean series. For those who want to delve into the amazing and sometimes mysterious world of ocean life, these books are a wonderful resource filled with scientific fact and beautiful photography.
